Minimum uncertainty in momentum from Heisenberg principle

[ucdawg12]

I am having a real problem understanding what I'm supposed to do for this question:
The position of an electron (mass given) is located by a detector with an uncertainty of 1x10^-10m, calculate the minimum uncertainty in the momentum of the electron.

Now, I have no idea how to calculate uncertainty, I can't find it in my book and I can't even find it online, is there some way anyone can explain how I am supposed to calculate uncertainty? I'm not looking for an answer just how I should go about doing this.

Thanks

Well you should have learned the Heisenberg (forgive me if i spelled his name wrong) uncertainty principle if you were given a question like that.
